I see Railex has issued a press release stating that it has two trains per week leaving Delano starting this week. It says they leave on Wednesdays and Fridays. Unfortunately, it does not give departure times. I have yet to see any of those trains.
I found another press release/flyer (which makes me think of “Surf City”) that does give the departure time. It looks like I will be hanging out by the tracks Friday evening.

Whatever happened to two trains for Wallula?
